.TransiEnt.Basics.Functions.GasProperties.getMolarMasses_fromRecord

Information

1. Purpose of model

This function supplies the molar masses of the components passed by the input vector.

2. Level of detail, physical effects considered, and physical insight

No physical effects considered.

3. Limits of validity

(no remarks)

4. Interfaces

(no remarks), just input and output vectors.

5. Nomenclature

(no elements)

6. Governing Equations

No governing equations. The function just searches the name vector in the molar masses record for the component names passed. Then it returns the molar mass defined in the molar mass vector in the record.

7. Remarks for Usage

• To unify this function the input vector must contain shortened component names or chemical formulas for the components, e.g. "Methane", or "CH4"
• If there's no corresponding entry for the component in the molar masses record, the molar mass will be supplied as zero, which might cause troubles (e.g. division by zero)

8. Validation

No validation needed. Tested in check model "TransiEnt.Basics.Functions.GasProperties.Check.TestConvertMoleToMassFraction"

9. References

(no remarks)
